I'm looking for the schematic for a PA68-F.
It's a two high collection of
single width M series modules that implements the paper tape high speed
reader/punch control for positive bus machines.
Does anyone out there know where I can download this
document?
I believe what you are looking for begins on page 53/125 of this document:
